HARNESS-CONTROLLING MECHANISIVI FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 642,908, dated February 6, 1900.

Application tiled October 21, 1899. Serial No. 734,347. (No model.)

To all whom t may concern.-

j Be it known that we, GUsrAv KREMER and EMIL MoNHoF, citizens of the United States, residing in New York, (Brooklym) Kings county, State of New York, have invented certain new and useful Improvements in Adjustable Shaft-Motion Regulators for Looms for Weaving Hat-Bands; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention relates to looms, and it has reference particularly to that portion of a loom which is embodied in its harness-controlling mechanism.

The object of the invention is to so construct said harness-controlling mechanism of a loom, and particularly a loom of that class known as narrow-ware looms, that the action thereof will be rendered more even and uniform and devoid of unnecessary jar, that the action of said harness-controlling mechanism may be regulated and its effect on the weftthreads as the sheds are formed thus adjusted, and that said action of the harness-controlling mechanism will also be accelerated, so that said mechanism, at any rate, shall not be the part of a loom which shall act to interfere with vits prompt action and the attainment of high speed.

Harness-controlling mechanism constructed after the principles of our invention, as hereinafter described, will be found to produce goodssuperior in quality to that produced in looms having the ordinary harnesscontrolling mechanism. The goods will have an improved texture, assuming a fine luster and appearance.

The invention consists in the improved harness-controlling mechanism and in the combination and arrangement of the various parts thereof, substantially as will be hereinafter pointed out, and finally embodied in the clauses of the claim.

In the accompanying drawings We have clearly illustrated our invention, of which-- Figure l is a front view, the same being shown as mounted in operative position on a loom for weaving hat-bands, (the style of narrow-ware loom to which our invention is particularly applicable,) a sufficient portion whereof is illustrated for that purpose. Fig. 2 is a view in side elevation, the parts appearing slightly enlarged in comparison with the showing in Fig. l. Fig. 3 is an enlarged view of a detail viewed from the rear of the loom. Fig. 4 is a sectional view of another detail, and Figs. 5 and G are views in side elevation of two modifications.

The loom-frame is indicated by the reference character a, and it carries the usual breast-beam b and batten c, upon which latter is sustained, as usual, the shuttle-controlling mechanism. (Indicated at d.)

e is one of the several revoluble shafts that are employed ordinarily in a narrow-ware loom and which extends throughout the length thereof, and f is another but shorter shaft, also often employed, which is journaled in one of the end uprights of the loom-frame and is operatively connected to and adapted to be driven by the shaft e through gearing g h. This shaft f is sustained partly in bearing-brackets t', disposed outside of the frame, and arranged between said brackets and mounted on said shaft are cams j, against which are adapted to bear rollers k, carried on levers l, that are fulcrumed in a bracket m back of the brackets c', said levers extending subjacently with reference to the cams and being movable in a true vertical direction by virtue of a suitable guide n.

0 designates the harness, which is of any well-known construction, and 29 denotes the harnesscords, which in the usual manner extend vertically from the harness to and over pulleys q, that are journaled in adjustable brackets r, that the top rails of the loomframe sustains.

From the upper portion of the loom-frame projects outwardly over the cam -motion structure already described a pair of arms or brackets t, said arms having their upper edges correspondingly notched for the reception of preferably squared shafts u, the ends of said shafts being reduced to form trun- IOO nions t, which seat in the notches. Each shaft carries a sheave w, over which passes and to which is preferably secured by means of a pin or screw c a strap or band y, the endsof each strap being connected, respectively, to those cords for the particular harness to which it is adapted to transmit motion. On each of said shafts u is also mounted a pair of other sheaves. These sheaves appear as a double sheave .ein the drawings, Fig. 1-, the one being slightly larger than the other and their common hub a being provided with a set-screw b', whereby the double sheavc is adjustably secured on the shaft. The bore of the hub is of course squared to fit the shaft. Over one of the sheaves of each double sheave extends a belt orband c', the ends of which are connected to the upper ends of hook-rods d which carry removable Weights c at their lower ends, into which are screwed the threaded shanks of hooks c2, engaging eyes f, carried by thelevers l. By adjusting each hook in the weight the belt c may be maintained in effective engagement with either portion of the double sheave, and so the lift of the harness can be regulated.

It is customary at present to use instead of the sheaves described above jacks or heddlelevers; but it will be obvious that by the use of the sheaves the action of the harnesscontrolling mechanism will be rendered more even.

g designates a rod which is threaded and screwed into each shaft u, which it penctrates and in which it is sustained at an incline in the normal position of the shaft-JL'. c., that indicated in Figl. A binding-nut 71, helps to secure the rod in the position to which it is adjusted. The lower end of the rod carries a Weight i. Now by turning the rod in the shaft the position of its weight 'i' relatively tothe shaft will be altered, and so by this means the action of the harness-con trolling mechanism will be regulated to the fulfilment of those objects of invention which were enumerated in the 'introductory paragraphs hereof.

We show in Fig. 5 a means whereby in addition to the weighted and adjustable rods for regulating the action of the harness-controlling mechanism auxiliary elements are utilizedfor effecting this. A suitable frame j surmounts each bracket or arm t, and to the top bar k' of this frame,which is substantially parallel to the bracket, are connected, by means of a series of eyes Z on said bar, spiral springs fm. These springs are connected to the free ends of the rods g-z`. e., the ends without the weights-and they act to normally maintain the rods at an incline, as shown in Fig. 5. These springs not only assist the weighted rods in regulating the action of the harness-controlling mechanism, but eifect the prompt return of its parts to their respective rest positions.

In the modification shown in Fig. G the weighted rods are dispensed with and instead short threaded rods oare used, (being mounted, however, in the same manner in the shafts 10,) being controlled by spiral springs p'. Posts q' project downwardly from the top bar 7c of the frame j, their lower ends being in the fmorin of eyes i", which are in alinement with eyes s', formed in the upper ends of the rods o', and also with eyes t' on the side bars or uprights u of said frame. rl`he several eyes referred to are connected together by the above-mentioned springs p', which act to normally maintain the rods in the positions indicated in Fig. G. The action of this form of our mechanism can be controlled, of course, by simply adjusting the rods o in the shafts a and so changing the positions and pull of the springs.

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is-
